My research interest lies at the interface of ecology
and biogeography, and involves a wide range of spatial scales. Specifically, I
am interested in biodiversity, biogeography, plant community ecology, and plant
systematics.
My
research in biodiversity focuses on the understanding of biodiversity patterns
at all spatial scales from the globe to the microcosm. At a larger scale, I am
interested in searching for the factors that have caused the current
intercontinental patterns of vascular plant species richness in the Northern
Hemisphere. I am intrigued by the fact that species diversity of vascular
plants in eastern
My
biogeography work falls into both historical biogeography and ecological
biogeography. My research in historical biogeography focuses on spatial pattern
analyses of the Northern Hemisphere vascular plants within and between
continents. For example, one of my ongoing projects in historical biogeography
is to characterize distribution patterns of the North American vascular plants,
such as the floristic relationships between different latitudinal or
longitudinal zones within
My
research in the area of plant community ecology involves ecosystem
classification, the descriptive and correlative analysis of vegetation -
environment relationships, and species diversity patterns at the community
level. I am especially interested in investigating similarities and differences
in a variety of community attributes such as structure, species diversity, and
the composition of functional types between plant communities of similar
climates in geographically widely separate areas (especially in different
continents). One of my ongoing projects on this topic focuses on the temperate
broad-leaved forests in eastern
My
recent work on plant systematics focuses on biodiversity
informatics. I have been compiling an integrated electronic database for the
Northern Hemisphere vascular plants. This database has served as the backbone
for my researches on large-scale patterns of biodiversity and biogeography. I
am particularly interested in making an electronic database that can be useful
to both taxonomists and syntaxonomists.
